Question

A) Draw 3 water molecules using structural formulas and demonstrate how they would create hydrogen bonds with each other. Be sure to label the hydrogen bonds.

B) Be able to define/explain each of the following:

1. Hydrophilic:
2. Hydrophobic:
3. Hydrogen ion:
4. Hydroxide ion:
5. Hydronium ion:
6. Acid:
7. Base:
8. pH:
9. Buffer:

Answer 1

Hydrogen bond is formed between the electronegative oxygen of one water molecule and hydrogen atom of other water molecule.

Please look in the image for solution:

Bases are those substance which are bitter in taste and having pH more than 7.

pH is defined as the potenz ( power) of hydrogen ion concentration.

Buffer is the solution which tends to maintain the pH of the solution.

Please rate high.
